A magnet attracts a piece of iron. The iron can then attract another piece of iron. On the basis of domain alignment, explain what happens in each piece of iron.


Expert Answer

Step 1

A magnet when brought in contact with a piece of iron, produces a domain alignment in iron which creates a strong external magnetic field around it.

Step 2

This external magnetic field makes iron behave as if it is an original magnet. Now, for another piece of iron kept near t...
